Can anybody explain the difference between DVD-R and DVD+R media?  Thank you.

Theres little difference, DVD+R may be more stable/better, which is why its slightly more expensive..

Commercial Answer

The truth is that the two competing technologies use different formats. No single company "owns" DVD and both technologies have their "champions".

DVD-R/RW was developed by Pioneer. Based on CD-RW technology, it uses a similar pitch of the helix, mark length of the 'burn' for data, and rotation control. DVD-R/RW is supported by the DVD Forum, an industry-wide group of hardware and software developers, and computer peripheral manufacturers. The DVD-R format has been standardized in ECMA-279 by the Forum, but this is a private standard, not an 'industry' ISO standard like the CD-R/RW Red Book or Orange Book standard.

DVD+R/RW is also based on CD-RW technology. DVD+R/RW is supported by Sony, Philips, HP, Dell, Ricoh, Yamaha, and others, and has recently been endorsed by Microsoft. DVD+R/RW is not supported by the DVD Forum, but the Forum has no power to set industry standards, so it becomes a market-driven issue.

Technical Answer

DVD+R is a dvd disc that allows multiple layers for one disc where as dvd-r only allows one layer. They will not compete to become the de Facto standard, because they are both here to stay. Multi layer DVD+R can allow extra capacity per disc than DVD-R hence its high cost!

DVD+R has a better tracking system (phase alternating) which is both more reliable and easier to read (which means faster on some drives), and DVD+RW has a much better error detection system. Since DVD+R compatibility is now comparable to DVD-R, and the price difference is insignificant (and worth it), you should go for DVD+R.
